Employees are usually one of the most valuable parts of the business you're buying — and one of the areas where the legal exposure is easiest to underestimate. Employment liabilities don't always show up on a balance sheet the way a loan or a lease does, but they can be just as real once you're the one running the business.

This checklist walks through the main categories of employment risk an Ontario buyer should investigate before closing, organized so you can work through it with your lawyer item by item.

Continuity of Employment (ESA Section 9)

Frequently asked questions

If I don't hire any of the seller's employees, do I avoid all employment liability?

In an asset purchase, generally yes for the seller's existing obligations to those specific employees — but you should still confirm this with your lawyer, since the facts of the transition matter, and any employees you do hire may bring continuity considerations with them.

Can I negotiate a non-compete with the seller as part of closing?

Often yes, if the seller is becoming an employee of your business as part of the deal — that's one of the two recognized exceptions to the general non-compete ban. A seller who is simply cashing out and walking away, without becoming your employee, may fall outside that exception, so this needs to be structured carefully.

What happens to employee benefits and pension plans in an asset deal?

This depends entirely on what's negotiated. Benefits and pension arrangements don't automatically transfer the way they might continue in a share deal, so buyers and sellers typically need to address this specifically in the purchase agreement.

Should I get an employment lawyer involved, or is my transaction lawyer enough?

For most deals, a transaction lawyer experienced in employment issues can handle this due diligence directly. For more complex workforces, layered benefits, or existing disputes, bringing in dedicated employment law input alongside the deal team is a reasonable extra step.
